yep, been there, done that... You could use the google eyes and get a small button for the nose, or as Anita suggested, glitter, felt,hand emb. or the poms, foam, or just use the candlewicking stitch. Whatever you do, I KNOW it will be adorable... Can't wait to see it. :)
It probably would not have been so bad if you had only done it to one. You could also use glitter glue, a felt nose, or the old fashioned way of hand embroidery to replace the missing features. See you had it all planned out to make each one different. lol
Of coarse - can't wait to see your moosee candy cane covers in projects - you always do cute projects. Hehehe!
